Maciej,

I have submitted a binutils defect report for this problem,
http://sourceware.org/bugzilla/show_bug.cgi?id=12287, and included what 
information I have so far.  I can show the problem using a small C++
program and their are two new failures in the GAS testsuite that show up
with this change.  The problem definitely starts with this checkin:

2010-12-01  Maciej W. Rozycki  <macro@codesourcery.com>

        * symbols.h (dot_symbol): New declaration.
        (dot_symbol_init): New prototype.
        * symbols.c (dot_symbol): New variable.
        (symbol_clone): Assert it's not dot_symbol being cloned.
        (dot_symbol_init): New function.
        (symbol_clone_if_forward_ref): Create a new temporary symbol
        when trying to clone dot_symbol.
        * expr.c (current_location): Refer to dot_symbol instead of
        making a new temporary symbol.
        * read.c (read_a_source_file): Update dot_symbol as we go.
        * as.c (main): Call dot_symbol_init.

But I don't know what is causing the change.
